Technical field
The utility model relates to the connection area of folding standpipe lower adaptor in folded bicycle folding standpipe installing area, particularly folding bicycle and front fork, especially a kind of folding standpipe lower adaptor and the connecting device that does not have outer tooth vertical pipe type front fork.
Background technology
The outer tooth vertical pipe type front fork of existing nothing is connected with folding standpipe lower adaptor, and dual mode is generally arranged: a kind of is in vertical tube of front fork, to make a call to an elastic material nut that is named as the heronsbill sheet, and this nut is thrown into through the external force flush fit, though tight still not because of fixed; Another kind is the nut of a similar heronsbill sheet of weldering in vertical tube of front fork, compresses lower adaptor and a tubular axis and holds and be connected on the vehicle frame head pipe through connecting screw then; If when compressing the heronsbill sheet with external force, because the heronsbill sheet enters by spring pressure, rather than fixing, be drawn out easily when big stressed, so just cause danger to the bicyclist; If with the mode of welded nut with nut weldering production technology trouble then in vertical tube of front fork extremely, if nut has been gone bad also very inconvenience in the time of will changing.
The utility model content
Be to exist the inconvenience of ride dangerous or repair and replacement to above-mentioned folding standpipe lower adaptor and the outer tooth vertical pipe type front fork connection mode of nothing the order of the utility model; It is good to design a kind of intensity, processes easily and folding standpipe lower adaptor that convenient for maintaining is changed and the connecting device that does not have outer tooth vertical pipe type front fork.
The technical scheme that the utility model solves the problems of the technologies described above is:
A kind of folding standpipe lower adaptor and the connecting device that does not have outer tooth vertical pipe type front fork; Comprise: forcing screw, pad, folding standpipe lower adaptor, clamp screw, head pipe bowl group bearing, interior tooth front fork and inner nut; Forcing screw, pad, folding standpipe lower adaptor, head pipe bowl group bearing are nested with successively on interior tooth front fork; Be provided with negative thread in the vertical tube of front fork, inner nut is provided with outside thread, and inner nut is threaded with vertical tube of front fork; The inner nut midway location is provided with screw again, and inner nut is threaded with forcing screw through screw.
As preferably; Be equipped with vehicle frame head pipe on the vertical tube of front fork, head pipe bowl group bearing is two, is in the two ends of vehicle frame head pipe when being nested with on the vertical tube of front fork; The bowl face of head pipe bowl group bearing is relative, and the outer end of head pipe bowl group bearing joins with the plain cushion that is nested with on vertical tube of front fork.
As preferably, fold the upper end position that is in vehicle frame head pipe when the standpipe lower adaptor is nested with on the vertical tube of front fork, folding standpipe lower adaptor has been connected through the hinge and has renovated.
As preferably, the side of folding standpipe lower adaptor offers clip slot, and the parallel axes of clip slot and folding standpipe lower adaptor, clip slot intermediate vertical are equipped with clamp screw and clamp clip slot.
As preferably, inner nut also is provided with the hexagonal hole that makes things convenient for instrument to use, and hexagonal hole communicates with screw in the middle of the inner nut, and the inscribed circle diameter of hexagonal hole is greater than the external diameter of screw.
As preferably, the periphery of pad is provided with flanging, and flanging will fold the upper surface that standpipe lower adaptor, head pipe bowl group bearing are pressed to vehicle frame head pipe.
The beneficial effect of the utility model:
Because inner nut is to be threaded with the interior tooth of vertical tube of front fork, not fixing the weldering extremely in inside, inner nut also is provided with the square hole when making things convenient for the instrument dismounting, is threaded like this to have reached higher intensity, flexibly the also convenient follow-up maintain and replace of mounting means.
